Notes:
(i) Configurations within each group of 4, or with common symbols ($\alpha$, $\beta$, $\gamma$, $\delta$ or $\varepsilon$), form complementary sets for multi-day observations. [This is for single-frequency observations. For a more sophisticated approach see section on bandwidth and multi-frequency synthesis.]
(ii) Antenna #6 sits permanently on station W392. Baselines to this antenna (the last 5 columns) are shown for all configurations, but form part of a designed array only for configurations 6.0A to 6.0D.
(iii)  Prior to July 1996, the 122B configuration was referred to as 120 and the 122A configuration was known as 122.
